To all whom it may concern:

Be it known that we, JOSEPH J. WALSER and CHARLES A. Dnnssnn', citizens of the United States, residing, respectively, at Chicago and Glencoe, both in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Mechanism for Renewing the Web in a Printing- Press and fonRegulating the Run of the Same Through the Press, of which the following is a specification, reference being had to the accompanying drawings.

Our invention has to do with printing presses and analogous machines in which the paper to be printed on is supplied from. one or more rolls, and it has for one of its objects to provide means for automatically maintaining a continuous supply of web to any given set of printingmechanism by antomatically attaching the lead end of the web from a fresh roll to the end portion of the web in useand introducing the fresh web into the press without stopping the latter. Another object is to provide mecha nism by which the press will be automatically slowed down preparatory to the the fresh roll.

automatic pasting of the end of the web of the fresh roll to the nearly exhausted web of the roll in use; also to provide means by which the press when automatically slowed down to any desired speed may be run at slow speed as long asmay be desired. A further object is to provide mechanism for positively feedingthe newlyattached web from the fresh roll to the printing mechanism operating upon it until the attached end shall have been carried far enough into the press to prevent strain upon the webs at the point of attachment, thereby insuring the proper feeding of the lead end of the fresh roll into the press; and more specifically, to provide new and improved mechanism by which a motor normally used as a braking motor to control the tension of the web may be automatically temporarily driven in the same direction as the web roll in order to assist in starting the web into the press. for the purpose stated. Another object of our invention is to provide automatic means for severing the web of the'old or exhausted roll behind the line of paste.

by which it is connected to the lead end of We accomplish these objects as illustrated in the drawings and as grammatically, the roller boxes, for the sake of clearness, being shown in separated views, one a side elevation and just above it a sectional view; I Fig. 2 is a continuation to the right of the press partly illustrated in Fig. 1;

Referring to the drawings,. I 7 indicates a part of the frame of the press. .8 indicates a web-roll, the web of.

which is drawn through the press by" the printing-couples and other forwarding rollers hereinafter described in the direction indicated by the arrows. 9 indicates a motor, which is concentric with the roll-shaft 280 upon which the web-roll .8 is mounted andsecured in the usual way. The rollshaft'QSOis journaled in suitable bearings, as'281, in the frame .7 of the press and is ner of mounting one of the solenoids to per- I morement of the arms will'move both the naled in the framework 7.

movable longitudinally of itself in said bearings. '282 indicates a friction clutch member which is secure-d upon one'end of the shaft 280, exterior to the framework of the press, and is provided witha circumferential groove 283. Themot'or 9 is mounted upon a carriage 284 which is suitably supported upon a bracket 285 of the framework so as 'toslide'tliereon in either direction and in the same direction as the rollshaft 280. 286 indicates the shaft of the motor 9, which is in line with the shaft 280 and is providedwith a member 287 rigidly secured to said shaft and provided with'a circumferential groove 288. 289 indicates a second friction clutch-member adapted to cooperate with the friction clutch-member 282 and featheredupon the shaft-286 so as to slide thereon toward and away from-the member 287. 290 indicates spiral springs which are placed-between the member 287 and friction clutch-member 289 and tend-to yiel'dingly hold member 287 and friction clutch-member 289 apart. The motor carriage'284 is'provided with a rack-bar 291 wlnch is engaged by a gear 292, mounted in the carriage 285' on-a shaft 293. 294'indicates a beveled gear on the shaft 293, which engages with a beveled gear 295 fixed on the end of a shaft 296 which is journaled at one endin a suitable bearing,'as'297, and

at the other end in a sleeve 298, which is itself journaled in a hub 299 which isjour- 300-301 indicate arms whose upper ends are adapted to engage grooves 283 and 288, respectively, and 'by'means of collars 302303 are mounted on a screw-threaded shaft 304 which is journaled at one end inthe framework 7,

and at the other end in' a suitable bracket,

as 305, mounted on the'frame of the machine. This shaft may be turnedby a-handwheel, as 306, or by means of a hand wh'eel 307 on shaft 308 mounted in bracket 309 and carrying at' its upper end agear 310, which meshes with the gear 311'on the shaft 304. The shaft'304 is screw-threaded so that by its rotation the arms 300-301 may be moved toward the left or right. When engaged with the grooves 283 and 288, such roll-shaft 2 and the '-motor.9 toward one side or the other soas to properly adjust "the roll upon the machine without'changing 'th'e'tension of springs 290. 312 indicates a cross-arm which connects arms 300 and 301 and which is connected with a rock-arm 313 "feathered 'upon sleeve 298. The rocking of the sleeve 298, so as'to move the arm 313 outward, will free the arms 300' and 301 a from the grooves, permitting the motor "to belmoved independently of the rollshaft. 314 'indicat'es'a lever which is secu'redtoh'ub 299 and which is provided with rods 315-816 which are adapted to engage,

respectively, with suitable notches oh shaft 296 and sleeve 298,'and are operated by the usual handles 3l7318, respectively, so that the lever 314 may be 0 eratively-connected with or'disconnected said sleeve. When the handle 318 is "grasped and the lever 3 14 is drawn backward, the rod 316 engages sleeve 298 and causes the same to rotate, swinging out rom said shaft and rock-arm 313 and freeing arms 300 and 301 from engagement with the clutch-members. \Vhen the handle 317 isgrasped, rod 315 is caused to engage shaft 296 so that movement of lever 314 rotates said shaft, and

through gears 293*295 rotates gear 292,

which is in mesh with rack-bar 291. -The motor is thusmoved to the right, freeing the friction clutch-member 289 from the friction clutch-member 282 so that the rollshaft can be removed from the bearings. The inotor is connected with electrical circuits, hereinafter described, and is designed and constructed so that by the operation of devices hereinafter described, it may first be run in the same direction with the roll so as to assist in feeding the web into the press to the desired extent, and may then 'be automatically reversed so as to run in the opposite direction to that of the roll and operate as a suitable brake on the roll to insure proper tension of the web. The speonic-mechanism for mounting the motor and the roll-spindle forms the subject-matter of rolland motor 1011 are intended. for use in place of the roll and motor 8-9 when the ,Web from the roll 8 is exhausted, and as unnecessary. p

12 indicates a box suitably qnounted in the frame of the machinein advance of the 'roll 8. 13 indicatesa roller whose bearings 14 are slidingly mounted in the box '12 so as to be free to rise and fall therein. In Fig. 1 three different positions of this roller are shown, two of them in dotted lines. '15 indicates buffer-springs which are located in the bottom of the roller-boxes 12 and whose weight of the roller 13 and its connections, so that when the paper is pulled through the press and the diameter of the roll 8 'diminishes,}the roller 13 is gradually lifted in the boxes 12, as is indicated by dotted lines in Fig. 1. The roller bearing 14 supports at one side of the box 12, contact-arms l6 and 17 (see Fig. *4), and at the other side of said box contact-arms 18 and 19 (see Fig.5), which are separated from each other and which are carried up and. down by the movement of the roller 13. 19 20 indicate contact strips upon one side of the roller-box 12, which are brought into electrical contact with one another by the arm 16 as the roller moves up in its box, and are of appropriate length so that the contact may be made 'at any suitable distance in the rise of the roller. 21 indicates an electrical contact-block upon one side of the box 12 which is adapted to be brought into electrical contact witlf'contact 17 when the -roller rises to the highest permissible distance in the box 12. 22 indicates a con tact-bar upon the other side of the box 12 which is adapted to be brought into electrical contact with the bar 18 as the roller rises. 23 indicates contacts, on the same side of the box 12 as contact-bar 22, which are connected with one another by a series of resistances 24 and are adapted to be brought into electrical contact with the end of the contact-bar 18, whereby, when the roller is raised, contact-bar 22 is brought successively into electrical connection with the blocks 23, thereby introducing successively more resistance into the circuit, hereinafter described, as the roller rises. 25 indicates an electrical contact-block, located upon the same side ofthe box 12 as the contact-bar 22 and contact-blocks 23, which is adapted to be brought into electrical contact with contact-bar 19 when the roller reaches the extreme upper limit of its movement;

Of course, it will be understood that each box, one on each side of the web. It is neccss'ary to provide only one box and one roller-bearing with the contacts described, and the box on the other side is like the box shown except that it has no contacts. From roller 13 the paper passes between boxes 26 which are suitably mounted in the frame of the machine upon each side of the web of paper. mounted in any approved manner in the framework'of the press above the boxes 26. The solenoids 27 are provided with cores 28 which, when'the solenoids are excited,'.will rise in the solenoids. 29 indicates'blocks which are slidingly mounted in the boxes 26 and connected with the cores 28. 30 indicates a wire knife which is stretched between the'blocks 29 below the web of paper and. is adapted, when the blocks are raised by the action of the solenoid, to sever the web' of paper. From between the boxes 26 the web passes over tension roller 31 and thence downward between rollers 32-33, which are normally supported as will be hereinafter 27 indicates solenoids suitably more fully described, and between and over a series of rollers 34, between the form and impression cylinders 3536 of an wellknown printing mechanism, whichr orward the web and print upon one side thereof. On its way to the cylinders the web passes under arolle-r 37 which is mounted in suitable bearings, as 38, in roller-boxes 39 mounted in any suitable manner in the frame of the press. This roller is free to rise and fall in said boxes, and the boxes are provided at the bottom with springs 40. The

roller 37 is of such weight as to be supported by the tension of the web, so that as long as the web is running through the press the roller is held in its upper position in its boxes. The springs 40 are of suchlength and tension as to yield when theroller drops, as is hereinafter described, sufficiently to permit the roller by its momentum to make temporary contact between the con tacts hereinafter described, but to immeroller free from said contacts. '4l42 indicate electric contacts connected with circuits hereinafter described, and carried by the roller-bearing in one of the boxes 39. 4344 indicate electric contacts'jconnected with the circuits hereinafter described, and

adapted to be brought into electric contact, "respectively, with contacts 41 and 42 when spring, as pointed out above, however, is

such as to immediatelylift the roller sufficiently to separate said contacts, so that their engagement is only momentary. After passing between form and'impression cylinders 35 and 36, the web is led around be-v tween form and impression cylinders 45- 46, in the usual manner, around the usual guide rollers 47, under roller 48, upward over roller 49 and down over the usual former and folding mechanism 50. Roller 48 is mounted in roller-boxes 51 upon each side of the machine by means of suitable bearings 52 in suitable slots in the boxes 51, so as to rise and fall therein. The roller, normally, when no paper is there, will rest at the lower portion of the box, but when the press is in operation and the paper is running therethrough, the tension of the web is sufficient to lift the roller in the box. 53-5455 indicate contacts which are carried on' the roller-bearing at one side of the press-and rise and fall therewith: 56-57 58 indicate contacts, which are secured to one of the boxes 51 in register with contacts I diately thereafter, by its tension, raise the Q framework upon eachside of the web, and

535455. When the roller 48 is free-to drop, contact 53 is brought into electrical 1 roll.

contact with contact 56, contact 54 with contact 57, and contact 55 with contact 58. These contacts are respectively connected to electrical circuits, as hereinafter described.

59 indicates a resistance-box suitably mounted at any suitable portionofdahepress and having a resistance 60 moreor less of-which is cut into or out of electrical circuits-hereinafter described, by the swinging of a lever 61 of the usual type mounted on'saidresistance-box. One end of the-lever is incontact with the resistance-box in the Wellknown manner, and the other is connected by a link 62 with the bearing of therollerdS, whereby the up and down-movementhof the roller in its box causes a movement of-the lever over its resistance, cutting more or less resistance in or out of the circuits hereinafter described. The weight of the roller is sulficient to operate the lever.

It will be understood, of -course, that of the rolls 8 and lO-only one-is in use at a time, the other roll being an extra or reserve Coming then to roll 10, the paper from said roll passes ofi 'from the same in the'direction indicatedby the arrows in Figs. 1, 2 and 3, being drawn through the press when said roll is being printedirom, inthe usual manner by the operation of the printing mechanism and-forwarding rollers. 63

indioates-roll-boxes mounted upon each side of the machine exactly like roll-boxes; 12. 64

indicates a roller mounted in suitable:bearings, as 65, so as to slideup and down in a suitable slot in the box 63 exactly as does roller 13. 66 indicates-springs mounted in the bottom of theroller box 63 for thesame purpose as springs :15. The-roller 64 on these springs is free to move, andis held 'upby the tension of the web, exactly as is roller 13, so that as the roll 10 diminishes the roller islif-ted. gradually in-the boxes, three of the positions being shown, two in dotted lines,'in Fig. 1. The roller bearing is provided, upon each side of one-:of the boxes, with contacts which rise and fall 6) therewith, precisely like those described for roller 13 in box-12, which is operated bythe paper from paper roll 8, and one box 63 is provided with contacts andwresistances, x-

actlyli'ke box 12, above described, and operating in the same manner. In other words, Figs. 4 and 5 represent one box 12 for the upperroll of paper, and one box 63-for the lower roll of paper. The web of paper from roll 10-passes upward between boxes 67,

mounted in any suitable manner in the precisely like boxes 26, above described. 68

f-the solenoids, exactly as is the case with solenoids 27 above described. 70 indicates blocks slidingly mounted in boxes 67 and connected with cores 69, and provided with a wire knife 70 stretched across between them below the paper, and adapted, when 70 said blocks are raised'by the operation of the solenoids, to seve'rthe web. The web the paper from roll 10 takes from rollers 32 and 33 on. Rollers 32 and 33 are provided, respectively, with pins, or with any other suitable devices for temporarily engaging the lead end of either .of the webs. The roller 32 is mounted upon eccentric-bushings 76 by the turning of which said roller 32 may be liftedout of, or brought into,..contact with roller 33. 77 indicates a rockshaft suitably'journaled in the framework of the press, and having arms 78 and 79. The arm 78 is connected by a link 80 with the eccentric-bushing 76 so that when the shaft 77 is rocked by th rock-arm '79, the eccentric-bushing will be partially rotated in one direction or the other, -to raise or lower roller 32 into or out of frictional engagement with roller 33, so thatthe same .95 may be pressed together and simultaneously rotated b the frictional engagementof the paper passing between them. T hey are also pressed together sufficiently to cause the pasting together of the lead end of the new roll to the nearly exhausted roll, in the manner hereinafter described. The rock-arm 79 is connected by links 81 and .82, respectively, With-cores 83-84 of solenoids 85 86, whereby, by the energizing of .either of said solenoids, its core is drawn intothe solenoid, the arm 79 swung, and the eccentric-bushing 76 operated, to bring rollers 32 and into contact, or separate them, as hereinafter described. The solenoids are connected with, and operate through, circuits hereinafter described.

The operation and management of the paper-passing through the press -.will be hereinafter more fully described. For present purposes it is enough to say thatwhen roll 8 is nearly exhausted, the lead end of paper from roll 10 is broughtnnder roller I pasted along its upper forward margin. Rollers 32 and 33 being separated, the passing of the web from roll 8 has no effect upon the web from roll 10. By the electrically I operated mechanism hereinafter described when roll 8 has been reduced to such a-diameter that the roller 13 reaches its top position, the solenoid 85 is caused to operate,

swmging arm 79 to the left, rocking eccentric-bushing 76, and bringing roller 32 down into frictional contact with the paper and pressing it against roller 33; This causes the pasted edge of the under roll to adhere to the surface of the paper of the upper roll, which, at that moment, by the knife 30 and mechanism hereinafter more fully described, is severed, and thereupon paper from roll 10 is fed through the press. Meanwhile at a suitable time a new roll is placed in position in place of roll 8, and the lead edge of its web carried forward, impaled upon'the pins on roller 32, and pasted on its under side. The rollers 32 and 33 have been meanwhile separated, as hereinafter described, and consequently the passage of the aper from roll 10 through the press has no e ect upon the paper from roll 8 until the size of roll 10 is so diminished that the roller 64: reaches its topmost position, at which time, in the manner hereinafter described, the solenoid 85 is again energized, bringing rollers 32 and 33 again into frictional engagement, and causing the pastedv lead edge of roll 8 toadhere to the nearly exhausted roll 10, which is at the same moment severed by the action of the knife hereinafter described. The press thereupon prints upon the paper (if roll 8, which takes the place of the paper fi-om exhausted roll 10. So on the two rolls alternate through the press. In either case, whether paper from roll 10 is pasted to the nearly exhausted paper from roll 8, or whether the paper from new roll 8'is pasted to the nearly exhausted paper from roll 10,

the operation of solenoid to bring the rolls together is only temporary, lasting just long enough to paste the two webs together. As soon as this is accomplished the rollers are separated in the manner hereinafter more fully described, by the denergizing of solenoid 85, the energizing ofsolenoid 86, and the return of lever 79 to the normal position shown in the drawings, with the backward rotation of eccentric-bushing 76 and the separation of rollers 32 and 33.

It will be ob ious that this substitution of the paper from a new roll for that of an exhausted roll cannot be as. well accomplished, at least practically, if the pressisrunning at full speed, and it, therefore, bee comes practically desirable, in connection with the matters above described, to provide mechanism which will automatically slow down the press when the old roll is suffia new roll, and to maintain this slow speed until the webs are securely pasted together and the new roll is running into the press. We have, therefore, provided mechanism by which this is automatically accomplished, that is'to say, by which the press is automatically slowed down when the old roll is substantially exhausted, and is maintained 95 at the slow down speed until the new roll ciently exhausted and it is desired to insert- --.;121" 122 123 1241 125 126.

of paper is taken into the press, whereupon the press is again run at high speed. As was said above, our *device relates to presses driven by electric motors. indicates a motorof any suitable type, which is adapted, by any well-known means, to drive the press. 91 diagrammatically indicates the field and 92 the armature circuit of the motor. By means of a suitable controller 93, and a switch 94, the motor is connected with main circuit wires 95-96. The form of controller which we prefer to use is diagrammatically illustrated in Figs. 3 and 7, and will be hereinafter more fully described. In the form of controller which we have shown, 97 indicates a contact arm pivoted at a suitable point, as 98. 99-109 indicate arch-shaped contact-bars that are brought into electrical connection with each other by contact-block 101, at the end of contactarm 97, which block, as saidcontact-arm is swung, presses upon contact-arches 99 and 100 and connects the same with each other electrically. 102 indicates a contact-arch having resistance-blocks 103 of the usual form. The contact-arch 102 is adapted, when the lever 97 is swung, to .be brought into electrical contact withthe block 104 on said arm, to introduce current into the shunt field, and theresistance-blocks 103 are adapted to cut resistance in series, in the well- A arm of contact-lever 97, so that the same is swung back and forth by the energizing of one or the other of said solenoids. 113- 114-115 are solenoids mounted upon the frame of the controller, and provided, respectively, withcores 116-117-118, which have attached to them, respectively, switches 119-120-121, the solenoids operating in the usual way when energized, to lift their cores, which are adapted, respectively, to make. electrical contacts between contacts These switches are normally closed, and are opened only when the solenoids are energized to raise the cores, as hereinafter described. 127-128 indicate contacts near solenoid 114C, and adapted to be closed orbridged electrically by switch 120' when the core 117 is raised into solenoid 11 1. 129 indicates a resistance normally in series with solenoid 115. 130 indicates a solenoid having a core:

or stop 131, which, when solenoid 130 is not energized, normally projects above it in the path of contact-arm 97, and which, when the 'solenoid130- is energized, is drawn into the shifted so as to place the core 131 .at the 99, through desired point. spectively, on, buttons of any 132133-134 indicate, reoff and stop pushwell-known type, normally open and adapted, when closed, to complete electrical clrcuits as hereinafter described. 136 indicates a wire extending from the negative side of the switch 94 to a wire 137. 138 indicates a wire which passes to the on button 132 from the wire 137, and leads to, and connects with, the solenoid 107 and then passes from the solenoid to wire 139, which is connected by wire 140 to the positive side of the switch. When the switch 94 is closed and the on button is pushed in so as to make the connection through wire 138,, the current passes through solenoid 107, energizing the same, and causing it to draw into it the core 109; By any suitable retarding mechanism, which is not shown as it forms no part ofour present invention, the core 109 is caused to move slowly into'the solenoid. This causes the upper end of contactarm 97 to move to the right, connecting archbars 99 and 100 by the contact 101. The upper arch-bar 99 is connected by a wire 141 with negative wire 137 and when the block 101' connects arch-bars 99 and 100 electrically, the current passes across from block 101, to arch-bar 100, to

which is connected circuit wire 142. The

current then passes through circuit wire 142, across switch 126, which is normally closed, to solenoid 114, and thence down to the positive wire 139, energizing solenoid the core into it, and by means of the switch on the end of the core, electrically connects contacts 127-128. Con- "tact 127 is connected by wire 143 to the negative wire 137 Contact 128 is connected by circuit wire 144 to contact-arm 97, which,

- havingbeen swung over as above described,

brings contact-block 106 into electrical connection with armature resistance contacts 105, and block 104 into connection with archbar 102 and resistance blocks 103, from the latter of which the current goes by wire 145 to the shuntvfield 91, and thenceback to positive wire 139. The current also will pass from contact-arm 97, through block 106, through the armature resistance contacts 105 and thence by wire 146 to the motor armature 92, and thence by wire 145 back to the positive 139. The motor will thus be started slowly, its speed depending upon the amount of resistance 105 in circuit. The on push-button is normally immediately releasedfso as to throw the arm 97 only a short distance, and maintain the motor for a time at slow speed. \Vhen it is desired to'increase the speed the on button 132 is given another push, which moves the arm 97 farther to the right, cutting out more of the resistance and increasing the speed of the motor, the operation being repeated until all of the resistance 105 is cut out of the armature circuit, and resistance 103 is inserted into the shunt field circuit, when the motor will be runnin at full speed. In order to accomplish this the core 131 of the solenoid 130 must be pulled out of the way of contact-arm 97 whenever the on button is pressed, to allow said arm to pass it. 147 indicates a wire which is connected with the wire 138 near solenoid 107, and after connecting with solenoid 130, passes back' to the positive wire 139. Whenever the on button is pushed in, current passes from wire 138 by means of wire 147, through solenoid 130, and back to positive wire 139, energizing solenoid 130, and drawing the core 131 inward out of the way of contact-arm 97. \Vhenever the on button is released, of course, the circuit is broken, and the core 131 is caused to spring back into position by any suitable mechanism.

148 indicates a wire which passes from negative wire 137 to off button 133, thence to solenoid 108, thence to wire 145 and back to positive wire 139. Whenever the 0d button 133 is pushed in to close the circuit through wire 148, the solenoid 108 is energized, and its core 110 is drawn inward, swinging contact-arm 97 to the left and moving its upper end across contact-arches 99-100, resistance-blocks 103 and contactarch 102, and armature resistance contacts 105, until, it the button is pressed long enough, the arm 97 is moved so far tha its contact blocks disengage said arches and resistance blocks, cutting off electrical contact with the motor, and stopping the same. At the same time, the connection between arches 99 and 100 being broken, the solenoid 114 is also cut off from the circuit and denergized, allowing core 117 to drop, cutting ofl electrical contact between contact blocks 127 and 128. If, however, the off button 133 is only momentarily pushed, the contact-arm 97 is only swung part way, and resistance is thereby cut in and the motor slowed down. This slowing down movement of the arm 97 may, of course, be continued until the motor is stopped in the manner described. To do this, however, the block 131 of solenoid 130 must be got out of the Way. 150 indicates a Wire which connects contact block 122 with wire 148. 151 indicates a wire which connects block 121 with solenoid 130. When the switch 119 is closed, which is its normal condition, after passing through solenoid 130, the current passes by wire 147 to positive wire 139.

Thus whenever the off button is pushed,

the core 131 of the solenoid 130 is drawn into the solenoid out of the way of contactarm 97, permitting its movement as above described.

As above described, the solenoid 115 has in series with it resistance 129, which is eflective to prevent the raising of the core 118 when the resistance is in series with the solenoid, but does not prevent said solenoid from holding up its core when it has been raised by the cutting out of the resistance, as hereinafter described. When the block 101- is in operative position, the circuit is as follows: from negative wire.-137- by wire 141, arch arms 99 and 100, and wire 142 to wire 152, through resistance 129, through solenoid 115;, and through Wire 153 back to positive 139. 154 indicates a wire which extends from one of the contacts of stop button 134 to wire 152 at one side of resistance 129. Wire 155 connects with the other contact of button 134, and with the other side of the resistance 129. Consequently when the button 134 is pressed in, wires 154 and 155 are connected thereby, and the current then passes from wire 142 to wire 152 through wire 154, to push-button 134, to wire 155, and thence upward and through the solenoid 115, cutting out the resistance 129, and thence back to positive. When the core 118 is drawn up, the switch 121 is moved away from the contacts 125-126, and the circuit through wire 142 is broken, which deenergizes'coil 114, and allows its core 117 to drop, opening the circuit between con I tacts 127 and 128, and breaking the circuit tion that the pressing of the ""on through contact-arm 97 to the motor. When this core 117 falls it completes the circuit between contacts. 123 and 124. 156

is a wire connecting contact 123 with wire 148, which passes to solenoid 108 as above described. The dropping, therefore, of core 117 causes the energizing of solenoid 108, pulling in the core 110, with the result above described. At the same time current passes through wire 148, across contacts 121 122 by switch 119, to wire 151, which energizes solenoid 130, and pulls its core 131 out of the way of the arm 97, in the manner above described.

It will be obvious from the above descripbutton will cause the motor to operate, starting the press and pulling the. paper through and the arm 97 can,

it; also that the pushing of the 0d button will slow down the press, and'ultimately stop it, together with the web, which is in all cases pulled through the press in the usual manner, by its engagement with the printing couples and the usual forwarding rollers. It is also obvious that by pushing the stop button 134 the press may be immediately stoppedJ e As the roll of paper 8 diminishes in diameter the path of the paper gradually rises, lifting with it roll 13 in the frame 12 and carrying up the contacts 1617-18 19, which are attached'to the, roller-bearing above described. When the size of the roll has so diminished that it becomes necessary to insert a new roll of paper into the press,

and the roller 13 has been lifted to a point near the top ofits boxes, the contact-arm 16 engages contacts 19 and 20, connecting the' -is connected by wire 163, and wire 164 to wire 148, and through coil 108 and wire 164", to the positive wire 139, as bestsh'own in Figs. 1, 2 and 3. The electrical bridging, therefore, of blocks 19 and 20 causes current to pass through the circuit. wires above described, energizing coil 108, swinging the upper end of contact-arm 97 to the left, and thus slowing down the motor 90. In this case, however, the block 131 stands in the path of the arm 97, limiting its motion. At the same time, current passes from wire 163 to solenoid 113, and thence by wires 164 and 145 to positive wire 139. This energizes solenoid 113, and raising the core 116, breaks the circuit between contacts 122 and 121,

thereby preventing current from flowing through solenoid 130. The core 131 will accordingly remain in its projected position,

therefore, move backward only until it comes in contact with said core, which, as has been said above, is adjustably placed in the path of the said arm. The motor, therefore, will not be stopped, but will only be sloweddown, and continue to run at a low speed. In other words, the bridging of contacts 19 and 20 by arm 16 on the rising of the roller, will only result in a'slowing down of the motor and. not in a stoppage thereof, and this occurs when the roll 8 has diminished to the point at which it is necessary to' run a new roll into the press. Before this point has been reached, as has been described above, the lead edge of the paper from roll 10 will have been brought up and secured to the securing devices, such as pins, on roller 33,

which, being an idler roller and moved only I by the friction of the paper, simply suspends the paper from roll 10 thereon until roll 82 is brought into frictional contact with it. Paste is then applied to the upper surface of thelead edge of the paper from roll 10, and the paper is ready to be pasted to the paper from roll 8 when the proper point is reached, the press having been slowed own to suitable speed as has been described above. As the roller 13 comes to the top of its movement by the substantial exhausting of the paper on roll 8, as above described, contact 19 is brought into electrical contact with contact 25. Contact 25 of the upper box 12 is connected to circuit wire 165, and contact 19 to circuit wire 166. Wire 165 connects with wire 167, which leads through one side of switch 168, to wire 169, above middle solenoid 114 to contact 128, thence acrossthe contact 128, when the solenoid is energized and the switch closed, to 127, and thence by wire 14:3 to negative wire 137. Wire 166 leads from contact 19 to solenoid 85, through solenoid 85, thence by wire 166 to the positive side of switch 168, and thence by wire 169 to the positive wire 139, as is shown in Fig. 3. The bridging of contacts 19 and 25, and the closing of this circuit, will energize solenoid 85, drawing inward its core '83, rocking the arm 79 to the left, and by means of arms 78 and link 80, rotating eccentric-bushing 76, and moving roller 32 downward into frictional contact with the paper and roller 33. Thereby, as explained above, the pasted lead edge of the paper from roll 10 is pasted to the under side of the paper from roll 8, and the two begin to move forward through the press together, thereby carrying the new paper from roll 10 through the press in place of the paperfrom roll 8.

It is obvious that as soon as the pasting is done, and the paper from the new roll begins running into the press, the paper from the old roll must be severed behind the paste line Referring to Figs. 1 and 8, 170 indicates a reversing switch, which, when the paper from roll 8 is being used, will be-in the position shown in dotted lines in Fig. 1. The operation of this reversing switch effects other purposes which will be hereinafter described. 171-172173174 indicate contact-points, and when the lever 170 is in the position shown in dotted lines in Fig.1, the contacts 173174: are electrically connected by a block 175 on the end of said lever. Referring to Fig. 2, 176-177 indicate switches which are located at one end of core 83, which are adapted, respectively, to electrically connect contacts 178 and 179, and contacts 180 and 182, and op- I erate to close sai'd contacts when said core is moved inward into the solenoid 85. Contact 17 1-(see Fig. 1) is connected by wire spindle, and

183 with circuit wire 167, which, as above described, leads to the negative side of switch 168. Contact 173 is connected by wire 184 to contact 179. When the switch 176 is closed, contacts 178 and 179 are connected, and the current is led from 178, by circuit wire 185, which connects through solenoid 27, and wire 185, to wire 166, which, as above described, connects with the positive side of the circuit. When solenoid is energized, as described above, so as to draw core 83 into it, the switch 76 makes connection between contacts 178 and 179, and the current thereby flows through solenoid 27, energizing the same, drawing up its core, and causing knife 30 to rise and sever the paper of roll 8 behind the line at which it is pasted to the paper from roll 10, as above described. The printing press thereupon prints from roll 10. The roll what is left of roll 8, may then be removed and a new roll substituted therefor, to be run into the press when the roll 10 is substantially exhausted.

When the coils 27 are energized, as above described, raising their cores, switch 186 is operated to make electrical connection between contacts 187 and 188. Contact 188 is connected by wire 189 to wire 167, which, as explained above, is connected with the negative side of the main circuit. Contact 187 is connected by wire 190 with solenoid 86, and thence to wire 166, which, as eX- plained above, leads to the positive side of the main circuit. The movement, therefore, which causes the severing of the paper, causes the closing of switch 186, and energizes solenoid 86, which, by drawing its core inward, moves the arm 79 to the right, and rotates the eccentric-bushing 76 in the opposite direction, immediately separating rollers 32 and 33. The severing of the paper from web 8, described above, of course, relieves its tension, and roller 12 thereupon drops to its original position, which breaks the circuit, and deenergizes solenoid 85, permitting solenoid 86 to act. Inasmuch as the deenergizing of solenoid 85, and the outward movement of its core, breaks the circuit in wire 185, the solenoids 27. are deenergized, permitting the ,knife to fall back to its original position, thus opening the switch 186, and denergizing solenoid 86, leaving solenoid 85 free to act at the next operation. The paper from roll 10 will now be running through the press, and a new roll 8 may be put in place. With the ex ception that it 1s connected by different circuit wires, which will be hereinafter described, it will be understood that the diminishing of the diameter of the paper on roll 10 acts in precisely the same way as the diminishing of the paper on roll 8, above described, so that when said roll 10 is practically exhausted, the motor is automatically slowed and the speed of the pressreduced to permit the pasting of the lead edge of the new roll 8v to the practically exhausted roll 10. The consumption of roll 10 operates to lift roller 64 in its box 63, and to cause current to flow through wires 160 and 161 to wires 162 and 163, to slow down the prlelss in exactly the same way as in case of r0 8.

The construction byvwhich' the lead edge of the new roll 8 is pasted to the paper from roll 10 when the same is substantially exhausted is as follows: Contact 19, on the contact-arm carried by the lower roller hearing is brought into electrical contact with contact 25 when the roller 64 reaches the top. Contact 19 of the lower roller 64 is connected by wire 191, to coil 85 and by wire 166 to the positive side of the main circuit. Contact 25 on box63 'is connected by wire 192 and wire 167- with the negative side of the main circuit. The rising of the roller 64, therefore, to its top position, energizes solenoid 85, and closes together rollers 32 and 33, in precisely the manner described. above, thus forcing together the pasted edge of the web from the new roll 8 and the paper from roll 10. The roll 8 is prepared for this operation in the manner described, except that the paste is applied to its under surface. a

193 indicates a reversing. switch, which, when roll 10 is running through the press,- is in'the position shown inldotted lines in Fig. 2. A contact-block 194 on the end of the switch operates, when the switch is in a certain position, to electrically connect contacts 195 and 196. The manner in which the switch 193 is moved to such position,which is indicated by dotted lines, will Contact 195 connected by wire 197 with wire 192, and

be described hereinafter.

then to wire 167 which, as above described, is connected with the negative side of the main circuit; Contact 196 is connected by wire 198 to contact 180, and when the switch 177 is closed by the energizing of the solenoid 85, as above described, it connects with solenoids 68 and by wire 166 with the maincircuit. The energizing of the solenoid 85, which brings together rollers 32 and 33, as above described, closes switch,17 7 and energizes solenoids'68, rais ing their cores, and lifting the knife to sever thepaper from the web 10 behind the pasted joint. 199 indicates a switch which is located in theupper end of one of the solenoids 68, and is lifted by the upward movement of the core of said solenoid to electrically connect contacts 200 and 201.

Contact 201 is connected bywire 202 with wire 167, which, as. described above, 'connects with the negative side of the main circuit. Contact 200 is connected by wire 203 with solenoid 86, and thence to wire 196,

i the positive side of switch 168.

thence by wire 229 to resistance 60 whose connection with the main circuit has been described above. The passing of the current through the solenoid 86 operates, as described above, to separate rollers 32 and 33. Just as was the case with roller 13, above described, the severing of the web re .leases its tension, roller 64 drops and the solenoids are deenergized as above described. We now have the paper from the new web roll 8 running through the press, and the exhausted roll 10 may be removed --and a new'roll substituted, the operation being repeated be desired.

The reversing switch 170 carries upon it not only the contact block 175, for the purpose above described, but also contactfrom time to time as may blocks 205206, which respectively operate,

lever out of the position shown in solid lines, and into the position shown in dotted lines in Fig. 1. 217 indicates a solenoid havinga core 218, which carries a switch 219 on' its lower end. 220 indicates a-resistance adapted to be placed in series with solenoid 217, and to operate, when so connected, to prevent said solenoid'from raising its core 218, but allowing enough current to flow through said solenoid to hold the core up after it has been raised. When the core is down in its normal position, the switch 219 makes contact between contacts 221 and 222. 22'3224 indicate contacts which are adapted to be closed by the switch 219 when the solenoid 217 is energized sufliciently to raise its core.

-225-226 indicate wires which are connected with the shunt field, and 227228 wires which are connected with the armature of motor 9. Wire 226 connects with Wire 225 connects with wire 166, which connects, as above described, with the positive side of switch 168. Wire 227 connects with archbar 209' on the reversing switch, and also with contact 171. Wire 228 is connected with the lowest resistance block 23 on the ances, as hereinafter described, and through sliding contact: 18, 'to contact-bar 22, and (see Fig. 3). When solenoid 114 is energized, it completes the circuit to the switch 168, as above described; The'negative wire 167 (see 1) is connected by wire 230 with block 221,

roller-box 12, as is best shown in Fig. 5, thence through one or more of the resistand a, switch 219 being, normally closed, is c'onnected through it to block 222, thence to wire 231, through solenoid 216, and by wire 232 to the positive side of switch 168.

.fore, the current passes This energizing of the solenoid 216 lifts plunger or .core 215, swinging the switch 17 0 in "a contra-clockwise direction, and connectin arch-bars 207-208by block 205, and arch-bars 209-210 by block 206. The circuit through the armature of motor 9 is thereby completed as follows z-Arch-bar 208 is connected by wire 233 with negative sistances 24, by wire 228 to one side of the 12 will be lifted, more and more resistance will be cut into the .armature circuit, and the armature, and from it bywire. 227 to archbar 209,. across block 206' to arch-bar 210, thence by wire 235 to wire 232, and thence to the positive side of the switch 168. The field already having been charged as above described, the circuit is completed and the motor runs in a contra-clockwise direction,- that is to say, in' the same. direction as the roll 8 which is being unwound,-there by assisting the paper in its progress into the press. It will be understood, of course,

that by any suitable retarding mechanism, which need not be described, as such devices are well known, the core 215 in solenoid 216 is caused to move slowly, at a regulated speed. As the 'core 215 continues to lift, the arm 170 is swung farther around until block 205 connects contacts 171 and 172, and block 206 connects contacts 213 and 214. Contact 172 is connected by wire 233 with wire 167, and with the negative side of switch 168. Contact 171 is connected by wire 237 to wire 227, which leads to one side of the armature of motor 9, thence through the armature, by wire 228, through the resistance 24, bysliding contact 18 to contact-bar 22, and thence to wire 229, the course of which has been above described. It'will be obvious that this reverses the direction of the current through the armature and the brake motor 9 thereu on turns in a clockwise direction, against t e rotation of the roll 8. It will also be obvious that as the roll of paper diminishes in size, roller speed of the motor 9 thereby diminished. Th1s .1 snecessary because it is necessary to dim nish the braking of the web roll as its size diminishes. 'As the web roll diminishes in size, since it is rotated by the 1111 of the press on the web, the leverage iminishes, and consequently a greater pull on the web is required. It is also obvious, therefore, that to maintain a proper tension the braking power should be correspondingly diminished, and this is done by slowing down the braking motor 9.

238 indicates a wire leading from negative wire 167 to resistance 220, which, as has been said above, is in series with solenoid 217, the circuit continuing by wire 239, to contact 240, and across switch 241 to contact 242. The switch 241, which is operated as hereinafter described, .is normally closed, and contact 242 is connected by wire 243 to wire 166, and to the positive side of the main circuit. When the roller 12 reaches the topmost limit of its movement, due to the diminution-of the paper roll, contact 17 and contact 21 are brought into electrical connection. (See Fig. 4.) Contact 17 has attached to it circuit wire 244, and contact 21 has attached to it wire 245. Wire 244 connects with wire 238 above the series resistance 220, and wire 245 connects to solenoid 217 below resistance 220. It thus results that when contacts 17 and 21 are connected, the circuit through solenoid 217 is from negative wire 167 through wires 238 and 244 to the contacts 17 and 21, thence by wire 245 to solenoid 21,7, thence by wire 239 to contact 240, across switch 241 to contact 242, by wire 243 to wire 166 and the positive side of the main circuit. This cuts out resistance 220 and fully energizes solenoid 217, which lifts its core, breaking contact of switch 219 with contacts 221 and 222, and consequently breaking the circuit through and deenergizing solenoid 216, so that its core drops, rotating arm 170 and stopping the braking motor 9. Roll 8 may then be removed.

The tension on roll 10 is regulated by motor 11 in precisely the same way, through the medium of the reversing switch lever 193, which is operated by solenoids 246 and 247 in the same manner that solenoids 216 and 217 operate reversing 1ever.170. The parts are substantially duplicates, and detailed description thereof is believed to be unnecessary. The arch-bars and contacts are connected by appropriate wires in substantially the same manner as the corresponding arch-bars and contacts in reversing mechanism 17 0, and operate in the same way. Solenoid 246 is energized by appropriate circuit connections, as follows: When the roller 13 reaches its topmost position, solenoid 217 is energized so as to lift switch 219, and connect contacts 223 and 224, as has been described. Contact 223, by means of wire 248, is connected to wire 167 which connects with the negative side of the circuit, and contact 224 is, connected by wire 249 to solenoid 246, which I energizes solenoid 246 and turns lever 193 into the position shown in dotted lines. It thereby brings it first over the arch-contacts corresponding with those above described in connection with arm 170, and the motor runs in the same direction as the paper until the lever reaches the position shown in dotted lines, when the rotation of the motor 11 is reversed and it acts as a brake. The paper from roll 10 thereupon runs through the press untilwhen it is substantially exhausted, the end of the web from a new roll 8 is pasted to it, as above described.

The diminishing of the diameter of the paper on roll 10 as the paper runs through the press, causes the rising of roller 64 in its box, which brings into play contact mechanism similar to that above described in connection with roller 13 and box 12, and efi'ects precisely the same results as on the paper from roll 8. When roller 64 is caused to reach the top limit of "its movement by the corresponding diminution of the roll 10, the solenoid 247 is energized by,

the cutting out of resistance 251, lifting switch 241, breaking the contact between blocks 240 and 242, and consequently the circuit through solenoid 217, which thereupon drops its core, 'denergizing solenoid 246, and the lever 193 thereupon automatically resumes the position shown in solid lines in Fig. 2, and the motor 11 stops. Meanwhile, as described above, a new roll 8 will have been placed in position, ready for attachment to roll 10, and will have been automatically substituted for the latter roll, in the manner hereinbefore explained. These operations may be continued, alternating from one roll to another, as long as may be desired.

As has been described above, and as is shown in Fig. 3, circuits are connected with resistance 60, and with arm 61 which is operated by the height of roller 48. As has been explained, this roller 48 is sustained by the tension of the paper, and will rise or fall from its normal position as the tension incidentally increases or diminishes during the operation of the press. lf the tension for any reason increases beyond the normal point, the roller rises, swinging downward the left-hand end of arm 61,- and cutting more of resistance 60 into the circuit, which causes the operating braking motor 9 or 11,- as the case may be, to run at less speed and consequently to have less braking power, thereby relieving the excessive tension. If, on the other hand, the tension relaxes below normal, the roller 48 drops and swings the lever 61 so as to cut out some of the resistance 60, thereby increasing the speed of the braking motor, increasing its braking power. 252 and 253' indicate wires connecting the arm 61 and resistance 60 with the motor 11. We thus provide for regulating the action of the braking motors by the tension of the web either in advanceof, or beyond the printing couples.

As long as the paper is running through the press, roller 48 will never drop to the extreme limit of its movement, as it will be sustained by the tension on the paper. If, however, a break in the paper should occur anywhere after passing the printing couple -46, the tension on the paper is, of course. at once released, which allows roller 48 to drop to its lowest position. This causes con tact 53 to make contact with contact 56. contact 54 to make contact with contact 57. and contact 55 to make contact with contact 58; These contacts are only diagrammatically illustrated in Fig. 3, but are preferably of the same form as the contacts used on the box 12, and shown in Figs. 4 and 5. Contact 53 is connected by Wire 254 to wire 154., and contact 56 is, connected by wire 255 to wire 155. The dropping of the roller .48, therefore, establishes electrical connection between contacts 53 and\56, and consequently makes connection between wires 154 and 155, short circuits resistance 129, and causes solenoid 115 to be energized and raise its core. This breaks the connection of switch 121 between pontacts 125 and 126, which deenergizes solenoid 114 causing it to drop its plunger, breaking the contact between contacts 127 and 128 and stopping the main driving motor. As the press does not stop instantly, in order to preventthe web from getting tangled up with the press, it is desired to immediately sever the paper in advance of the printing couples This is efi'ected by bringing contacts 54 and 57 together by the dropping of the roller 48. Assuming, therefore, for purposes of description, that it is roll 8 winch is running through the press when the break occurs, it will be remembered that when so running reversing switch 170 is in the osition shown in dotted lines in Fig. 1. ontact 54 is connected by wire 256 to contact 173, and contact 57, by wire 257,

is connected at point 258 (see Fig. 2) to wire 185 of solenoid 27, and through said solenoid, by wire 185, to the positive side of the main circuit, as above described. The circuit, therefore, is from negative wire 167, by wire 188, to contact 174, across contactblock 17 5 to contact 173, thence by wire 256 to contact-block 54,'through contact 57, by wire257 to'wire 185 of solenoid 27, and then to the positive side of the main circuit, thus completing the circuit, energizing the solenoid 27 and causing the hiife 30 to sever the paper on roll 8.

Contacts 55 and 58, by wires 257 and 258*, respectively, are connected in the same manner, through the contacts of reversing switch mechanism 198, to solenoid 68, energizing the same, and causing the risingof the m. to sever the paper wh roll 10? is being used. It will, therefore, be obvious that, whichever roll is being used, a break in the paper after passing the printing couples, will cause the roller 48 to drop and the paper to be severed back of the first prmting couple.

In case a break inthe paper occurs before it reaches the first printing couple 36, the press is automatically stopped by the falling of the roller 37. As above described, this roller 37 is held up by the tension of the paper, and when the paper breaks, the tension being destroyed, the roller 37 drops, causing contacts 41 and 43, and contacts 42 and 44, to be brought into electrical contact. This contact is only temporary because springs are of suflicient length and tension to hold roller 37 normally high enough to keep the contacts from being made, but when roller 37 drops there is sufficient momentum to cause the compression of the spring 40 and bring the contacts together. 259 indicates a wire which, through wire 254, connects contact 41 with wire. 154, (see ,Fig. 3), and 260 indicates a Wire which connects contact 4%with wire 255 and through it with wire 1 The falling of the roller so as to bring these two contacts together,

1 positive circuit.

- therefore, operates to stop the press, as they are connected to the same wires as'wlres 254 and 255, which operate to stop the press when roller 48 falls to its limit by a breakage of the web beyond the printing couples, asabove described. As the braking motors 9 and 10 ordinarily receive their current through the, same circuit as the main motor, in order that brake motor 9 or 11, as the case may be, shall, in case the web breaks,

continue running in a direction opposite to the rotation of the roll,'to wind the roll up and pull the broken paperback out of the press, the following instrumentalities are provided: 261 (Fig. 2) indicates a solenoid provided with a core 262 which carries switch 263. 265266 indicate contacts which are closed by the upward movement of switch 263. 269 indicates a resistance adapted to be connected in series with solenoid 261, and operating when so connected, to reduce the power of said solenoid sufficiently so that it will not operate to raise the core, but will hold the core up, after it has been lifted. The solenoid is made effective for lifting its core by short circuiting said resistance, the connections being as follows: 27 0 indicates a wire which. leads from the negative side of switch 168 to resistance 269, thence to coil 261, thence bywire 271 to switch 272, and thence by wire 273 to the positive side of switch 168 and the main 274 indicates a wire which is connected with wire 270 above the resistance 269, and connects with contact 42; 27 5 indicates a wire which leads from contact to coil 261. By this arrangement, when the contacts 42 and 44 are brought together,

resistance 269 is cut out, so that coil 261, energized sufficiently to lift its core 252 and make contact between contacts 265 and 266."

to the negative side of the main switch 94 and thence to the negative side of the circuit. The raising of the coreof the solenoid 261, therefore, completes the circuit through contacts 265 and 266, and thus the supply circuit to motors 9 and 11 is from the negative side of switch 94, through the contacts 265 and 266, by wire 27 6 to the negative side of switch 168, the positive connection remaining as before. Consequently the stopping of the press motor does not affect the motors 9 and 11, and whichever one has been running continues to run in the same direction until the switch 272 is opened. The opening of this switch, of course, breaks the circuit and deenergizes solenoid 261, permitting its core to drop, and breaking the circuit so that the brake motor stops.

We have shown our invention diagramconnection with one deck of a printing press, but it will be understood that we do not confine ourselves to the application of this mechanism to a single deck press, or to only one deck of a press, as it is obvious that it may be used'in a plural decked press adapted to print simultaneously from two or more webs, by simply duplicating as far as necessary the mechanism above described, with the exception of the motor and controller.

The operation of the apparatus described has been incidentally explained, but it may be well to summarize the general features of the operation. A web from one of the rolls, as 8, being placed in the press, and the switch 94 closed, the motor is started slowly by pressing the on button 132, and is driven at a low rate of speed until the paper is threaded through the press. By the further operation of the on button, the speed of the driving motor is increased, in the manner described,,until the press is printing at full speed. In starting the, mechanism the braking motor is at first run in the same direction as the roll, to assist in threading the paper, but as soon as the paper is led the necessary distance into the press, the rotation of the braking motor is reversed so that it then operates as a brake to control the rotation of the web roll. As the size of the roll diminishes, the bearing roller, as 13, is gradually lifted as the paper rises, so that more an more resistance is cut into the arf mature circuit of the braking motor, causing said motor to rotate with progressively di-' minishing speed, thus lessening its braking elfect in proportion to the decrease in the diameter of the paper roll. As said bear-- ing roller approaches the topv of its box, by the diminution of the roll to a predetermined point, coil 108 is energized by the 'electrical connection-of contacts 19 and 20 through-contact arm 16, which causes the" swinging of the controller-bar 97, in the manner above described, soas to cut more and more resistance into the circuit of the press driving motor, thus causing it to slow down and slowing down the speed of the press. The controller-bar 97 'cannot, however, move far enough to stop the presssince its movement is limited by the stop or core 131, which is position-to intercept it when it reaches apredetermined point correspond ing with the speed to which the press is to ing devices of the lower roller 33, which up to this point is separated from. the roller 32, and pasteis applied to the-upper surface of the new web near its leading edge. When the roll which is being used is substantially exhausted, the rising of the roller 13 to its topmost position caused thereby,

causes roller 32 to be lowered into frictional contact with roller 33, pressing the pasted edge of the under roll against the paper from the upper roll and causing its adherence thereto. At the same time the upper web is severed by the action of the'knife 30, as'above described, and the paper from the new roll is led into the press by its adherence to the paper of the old roll. The severing ,knife thereupon automatically .drops, and rollers 32 and 33 are separated.

By pressing the on button, the controller may. then be swung in the other direction,

. cutting out more and more resistance, until the driving motor is again running at full speed. ,When the new roll starts into the press its motor, as 11, is at first driven in the same direction as the roll, to assist in forwarding the roll, and prevent strain upon the pasted portion, but after a suitable in.- terval, the direction of rotation of the braking motor is reversedso that it acts as a brake. The proper tension on the web beyond theprinting couples is maintained by 2 the operation of roller 48, lever or switcharm 61 and resistance 59, as described above.

If the tension on the web is too great, the

lever is swung so as to cut more resistance into the circuit of the brake motor, which thereuppn decreases its speed,.diminishing its bra 'ng effect and compensating for and reducing the excessive tension. If the tension for any reason becomes too lax, the roller 48 drops, swinging the lever 61 so as to out outmore of the resistance 60, thus speeding the brake motor and increasing its braking effect. When the press is printing from the second roll, precisely the same results ensue as when printing from the first roll. When the second roll is nearly exhausted, the driving motor is slowed down by the rising of the web and the roller which bears upon it. The lead edge of a new roll 8 is secured to the upper roller 32, and paste applied, and the rollers are brought together to attach the new web to the old one in the manner above-described, the paper from the exhausted roll 1.0 being severed back of the paste line, and the new roll led through the press as before.

In case either of the webs should break I back of the printing couples, the breaking of the web causes the falling of roller Y37, and the consequent breaking of the driving motor circuit and the stoppage of the press.

In case the web breaks after leaving the printin couples, the-breakage of the web causes 1: e falling of roller 48, and the consequent breaking of the driving motor ciricuit and the stoppage of the press.

" The press can, of course, at any time be slowed down by the use of the off button 133 and the controllers above described, speeded up again by. the use of the on button 132, or immediately of the stop button 134.
